Successive topics

From 1984 to 1993

  • Hydrology and biogeochemistry  of semi-natural ecosystems (impacts of landuse (deciduous/conferous/grassland, acidification, p acid rain
  • hydrological (TOPMODEL) an biogeochemical (MAGIC) modelling.

From 1993 to 2000

  • Impacts of riparian buffer zones on nitrogen transfer and transformation in rural catchments (denitrification, Redox potential,  ecological engineering, water pathways).
  • Chemical and isotopical hydrograph separation (multitracing-EMMA-stable isotopes)
  • hydrological functionning of shallow groundwater catchments

From 2000

  • Integrated modelling of nitrogen transfer and transformation in agro-ecosystems.
  • Coupling of hydrological, crop and farm models.
  • development of spatialized agro-hydrological model (TNT2, CASIMOD'N, Nitroscape(with EGC Grignon research unit)
  • Participation to the development of a semi distributed nitrogen model (INCA, Univ Reading, UK)
  • modelling the hydrological and biogeochemical functionning of landscape structures (hedgerows, riparian  buffers)
  • DOC tranfer modelling.
